The present application provides a display panel including a non-displayregion 100 a and a GOA unit region 101 a in the non-display region 100a. The GOA unit region 101 a includes multi-level GOA units 101 arrangedin multiple columns, so that a plurality of GOA units 101 aredistributed in the non-display region 100 a with multiple columns.

Theoutput end is configured to output a scan signal when one of the GOAunits 101 responses to the turn-on signal and a clock signal received bythe input end.

The output ends of the plurality of GOA units 101 are all connected tothe scan lines in the display panel and are configured to transmit thescan signal to the display panel through the scan lines.

The turn-on signal includes a first turn-on signal STV and a secondturn-on signal. The first turn-on signal STV is configured to turn on afirst level GOA unit G₁ in the GOA units 101. Furthermore, the firstturn-on signal STV is configured to turn on the first level GOA unit G₁and a second level GOA unit G₂ in the GOA units 101. The second turn-onsignal is configured to turn on the rest of the GOA units 101. Thesecond turn-on signal can be transmitted individually or can be providedby the cascaded GOA units 101.

If the second turn-on signal is provided by the cascaded GOA units 101,the output end of a k-th level GOA unit G_(k) is connected to the inputends of subsequent q levels of the GOA units 101, so that a k-th levelscan signal S_(k) output from the k-th level GOA unit G_(k) is used as aturn-on signal of the subsequent q levels of GOA units 101, therebyturning on the subsequent q level of the GOA units 101.

Furthermore, the k-th level GOA unit G_(k) can be connected to inputends of previous q levels of the GOA units 101, so that the k-th levelscan signal S_(k) output from the k-th level GOA unit G_(k) is used asthe turn-off signal of the previous q levels of GOA units 101, therebyturning off the previous q level of the GOA units 101, wherein q=±1, ±2,±3, etc., q is determined as a positive integer to indicate that it isused in the subsequent q levels of the GOA units 101, and q isdetermined as a negative integer to indicate that it is used in theprevious q levels of the GOA units 101.

Specifically, if q=±1, the GOA unit region includes P levels of the GOAunits 101. The first level GOA unit G₁ in the GOA units 101 is turned onin response to the first turn-on signal STV and output a first levelscan signal S₁; the second level GOA unit G₂ in the GOA units 101 isturned on in response to the first level scan signal S₁ and output asecond level scan signal S₂; the first level GOA unit G₁ is turned offin response to the second level scan signal S₂; and a third level GOAunit G₃ is turned on in response to the second level scan signal S₂.Similarly, a k-th level GOA unit G_(k) is turned on in response to a(k-1)-th level scan signal S_(k-1) output from a (k-1)-th level GOA unitG_(k-1) and output a k-th level scan signal S_(k); the (k-1)-th levelGOA unit G_(k-1) is turned off in response to the k-th level scan signalS_(k) output from the k-th level GOA unit G_(k), a (k+1)-th level GOAunit G_(k+1) is turned on in response to the k-th level scan signalS_(k) output from the k-th level GOA unit G_(k) and output a (k+1)-thlevel scan signal S_(k+1); and the k-th level GOA unit G_(k) is turnedoff in response to the (k+1)-th level scan signal S_(k+1) output fromthe (k+1)-th level GOA unit G_(k+1). In this manner, the plurality ofGOA units 101 of the GOA unit region complete a cycle of work until aP-th level GOA unit in the GOA units 101 is turned on and output a P-thlevel scan signal S_(P). Because the first level GOA unit G₁ is turnedon in response to the first turn-on signal STV, k is greater than 1(k>1).

In FIGS. 2A to 2E and 3A to 3D, q=±2 is taken as an example fordescription. Specifically, the GOA unit region includes P levels of theGOA units 101. The first level GOA unit G₁ and the second level GOA unitG₂ in the GOA units 101 are turned on in response to the first turn-onsignal STV and respectively output a first level scan signal S₁ and asecond level scan signal S₂; the third level GOA unit G₃ is turned on inresponse to the first level scan signal S₁ output from the first levelGOA unit G₁ and output a third level scan signal S₃; the first level GOAunit G₁ is turned off in response to the third level scan signal S₃; anda fifth level GOA unit G₅ is turned on in response to the third levelscan signal S₃. Similarly, the k-th level GOA unit G_(k) is turned on inresponse to a (k-2)-th level scan signal S_(k-2) output from a (k-2)-thlevel GOA unit G_(k-2) and output the k-th level scan signal S_(k); the(k-2)-th level GOA unit G_(k-) ₂ is turned off in response to the k-thlevel scan signal S_(k) output from the k-th level GOA unit G_(k); a(k+2)-th level GOA unit G_(k+2) is turned on in response to the k-thlevel scan signal S_(k) output from the k-th level GOA unit G_(k) andoutput a (k+2)-the level scan signal S_(k+2); and the k-th level GOAunit G_(k) is turned off in response to the (k+2)-the level scan signalS_(k+2) output from the (k+2)-th level GOA unit G_(k+2). In this manner,the plurality of GOA units 101 of the GOA unit region complete a cycleof work until the P-th level GOA unit in the GOA units 101 is turned onand output the P-th level scan signal S_(P). Because the first level GOAunit G₁ and the second level GOA unit G₂ are turned on in response tothe first turn-on signal STV, k is greater than 2 (k>2).

Understandably, the plurality of GOA units are level-shifted from thefirst level to the P-th level, which means that after the first levelGOA unit G₁ is turned on in response to the first turn-on signal STV;the second level GOA unit G₂ is turned on in response to the firstturn-on signal STV; the third level GOA unit G₃ is turned on in responseto the first level scan signal S₁ output from the first level GOA unitG₁; a fourth level GOA unit G4 is turned on in response to the secondlevel scan signal S₂ output from the second level GOA unit G₂; and soon, until the P-th level GOA unit in the GOA units 101 is turned on inresponse to a (P-2)-th level scan signal S_(P-2) output from a (P-2)-thlevel GOA unit G_(P-2) and output the P-th level scan signal S_(P).

The clock signal is transmitted to the GOA units 101 through a clocksignal line connected to an input end of each of the GOA units 101.Furthermore, the input end of each of the GOA units 101 is connected toa plurality of clock signal lines, and moreover, the input end of eachof the GOA units 101 is connected to three clock signal lines.

Please refer to FIGS. 1B, 2A to 2E, and 3A to 3D, the GOA unit region101 a includes a first GOA unit region 102 a and a second GOA unitregion 103 a. The multi-level GOA units 101 in the first GOA unit region102 a are odd-numbered GOA units, and the multi-level GOA units 101 inthe second GOA unit region 103 a are even-numbered GOA units. As aresult, the plurality of GOA units 101 are evenly distributed in thefirst GOA unit region 102 a and the second GOA unit region 103 a.

In addition, when the display panel includes P levels of the GOA units101, the multi-level GOA units 101 positioned in the first GOA unitregion 102 a can be a previous P/2 levels of the GOA units 101, and themulti-level GOA units 101 positioned in the second GOA unit region 103 acan be a subsequent P/2 levels of the GOA units 101. Compared with aconfiguration that the previous P/2 levels of the GOA units 101 aredisposed in the first GOA unit region 102 a, a configuration, whichdisposed the multi-level odd-numbered GOA units in the first GOA unitregion 102 a and disposed the multi-level even-numbered GOA units in thesecond GOA unit region 103 a, can reduce wiring lengths between the P/2levels and the P/2+1 levels and reduce impedance of wirings.

A GOA unit atan i-th row and a j-th column is G_(2m(i-1)+2j-1), wherein i =1, 2, 3,..., n, j=1, 2, 3, ..., m, n>1, and m>1. Specifically, if the displaypanel includes P levels of the GOA units 101, n=2, 3, 4, 5, ..., P/4,..., P/2, etc., and m=2, 3, 4, 5, ..., P/4, ..., P/2, etc.

In the first GOA unit region 102 a, n×m levels of the GOA units 101 arearranged in the following manner:

$\begin{bmatrix}\text{G}_{1} & \text{G}_{3} & \cdots & \text{G}_{2\text{j}\text{−}\text{1}} & \cdots & \text{G}_{2\text{m-1}} \\\text{G}_{2\text{m+1}} & \text{G}_{2\text{m+3}} & \cdots & \text{G}_{2\text{m+2j}\text{−}\text{1}} & \cdots & \text{G}_{4\text{m}\text{−1}} \\\text{G}_{4\text{m+1}} & \text{G}_{4\text{m+3}} & \cdots & \text{G}_{4\text{m+2j-1}} & \cdots & \text{G}_{6\text{m-1}} \\ \vdots & \vdots & \vdots & \vdots & \vdots & \vdots \\\text{G}_{2\text{m}{({\text{i}\text{−1}})} + 1} & \text{G}_{2\text{m}{({\text{i}\text{−1}})} + 3} & \cdots & \text{G}_{2\text{m}{({\text{i}\text{−1}})} + 2\text{j}\text{−1}} & \cdots & \text{G}_{2\text{mi}\text{−1}} \\ \vdots & \vdots & \vdots & \vdots & \vdots & \vdots \\\text{G}_{2\text{m}{({\text{n}\text{−1}})} + 1} & \text{G}_{2\text{m}{({\text{n}\text{−1}})} + 3} & \cdots & \text{G}_{2\text{m}{({\text{n}\text{−1}})} + 2\text{j-1}} & \cdots & \text{G}_{2\text{mn}\text{−}\text{1}}\end{bmatrix}$

Specifically, in the first GOA unit region 102 a as shown in FIGS. 2A to2B, m=2 is taken as an example for description. In the plurality of GOAunits 101, the first level GOA unit G₁ and the third level GOA unit G₃are positioned in a first row, the fifth level GOA unit G₅ and a seventhlevel GOA G₇ are positioned in a second row.
